You question and example are incomplete. Read
https://stackoverflow.com/help/mcve and follow it by adding in the
missing definitions and printing the result. For example:
satellite_origin_list = []
satellite_dataread = '''\
hooray, usa
salud3, ussr
panda 33, china
'''.splitlines()
list2 = ['ray', 'and']
for line in satellite_dataread:
if any(i in line for i in list2):
line= line.strip()
satellite, country= line.split(',')
satellite_origin_list.append(country)
print(satellite_origin_list)
# prints
[' usa', ' china']
Now tell us what you think is wrong with this result, which is exactly
what I expected.
Note: you might want to unpack lines first and then test either
satellete or country separately.
